MOTOMETER-LAMP.

Specification of Letters Iatent.

Patented Aug. 2, 1921.

Application filed November 8, 1920. Serial No. 422,437.

To uw lwhom t may concer/n Be it known that I, JOHN R. Krimis, a citizen of the United States, and resident of 'Covingtoiu in the county of Kenton and State of Kentucky, have invented certain new and useful Improvements in Motometer- Lamps, of which the following is afull, clear, and exact description, reference being had to the accompanying drawings, for'nnng av )art of this specification.

vily invention relates to lamps for illuminating the motometer of an automobile so that the same is visible at night.

The location of the motometer on thc radiator cap of an automobile, which is, of course necessary, in. order that it may operate for the purpose designed, is such that its visibilityis at most times more' or less difficult, and this difficulty under faulty conditions of light becomes so great as to impair absolutely the utility of the device as few drivers will take the time and trouble to leave the vehicle and light the motometer artificially to obtain a reading. The principal object of the present invention is to overcome this diiliculty and to provide a lamp which is so located and adjusted as to be at all times available for the purpose of illuminating the instrument.

A further object of this invention is t provide in connection with a lamp suitable for the illumination of a motometer, an adjustable mounting for said lamp.

Other objects of the invention will appear from the following detailed description thereof.

ln tln` drawings: j Y

l-`igure l is a side elevation of the invention illustrating its mounting and use;

Fig. 2 is a. central'longitudinal view of the lamp;

3 is a front elevation ofthe invention as illustrated in. Fig. l, part of the motometer being .broken away to disclose features of the lamp mounting;

7Eig. 4 is a perspective of a modified mountino of the lamp standard on the radiator cap.

The. numeral l illustrates the radiator cap of an automobile, and 2 a motometer mounted on said cap in the usual manner.

Secured between the lower portion o1 tue motometer and the lock nut 3 thereof is an arm 4 upon theouter end of which a tubular standard 5 is secured by means of a nut 6. Arranged to telescope in the standard 5 is a rod 7 upon the free end of which a ring or head 8 is secured or integrally formed if desired. A set screw 9 secures the rod 7 in the standard vat the desired elevation.

Arranged to t in the head 8 is a. lamp barrel or socket 140, which is provided with the usual electrical connections for an ordinary plu 1l and bulb l2. rIhe front or lamp end of t 1e socket l0 is externallythreaded to receive a lamp shroud or guard 13 of ordinary construction. The'socket is adjustable, both longitudinally and rotatably in the head 8, and arrangement is made to secure it in desired adjustment by means of a set screw 14.

In Fig. 4 I have illustrated a modifiedv form of attachment of the standard 5 by means of rivets or bolts which secure it directly to the radiator cap.

From the foregoing description the nature and value of the present invention will be fully apparent to those familiar with the art to which the same appertains. When a motometer lamp of the kind described is rovided in connection with the instrument,

1t will be seen that provisior is made for the suitable illumination of the device at all times and under all conditions. By means of the vertical adjustments provided for in the tubular standard 5 and telescoping rod -7 provision is iliade whereby the lamp may be adapted tometers of various size, and the adjustability of the barrel or socket 10 in the. head 8 both longitudinal and rotary enable the operator to adjust the lamp so that its beams are thrown directly on the face of thev instrument. Y'

It will be understood that various modiications in the details of construction described maybe made without departing from the invention as above defined and as set forth in the appended claim.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent, is:

A motometer lamp, comprising in combination-With a motometel', a. tubular standard and rotatably adjustable therein, a set screw mounted adjacent sa'd motometer, a, rod arto secure said socket in desired ladjustment;

ranged t'telescope said standard, a set said socket being arranged to receive an 10 v screw to'secure said rod in desired adjustelectrical bulb and' an electrical plug, and ment in the standard, an annular head on electrical connections in said socket between thefree'end of said rod, a. socket arranged said plug and bulb.
